Demystifying the Wax Leaf Privet’s Growth Rate

The wax leaf privet (Ligustrum japonicum) is a versatile evergreen shrub that can be pruned into hedges, topiaries, screens, and small tree forms. Its adaptability and lush green foliage make it a go-to choice for many gardeners. But before planting, it’s important to understand the wax leaf privet’s growth rate so you can choose the right size and properly care for it. In this article, we’ll demystify the details around this plant’s growth habits.

An Overview of Growth

The wax leaf privet is considered a fast growing shrub. In ideal conditions it can achieve a growth rate of up to 2 feet per year when it’s young. The growth rate gradually slows as the plant matures. Here’s a quick overview

• Years 1-2: Up to 2 feet of new growth per year.
• Years 3-5: 1 to 1.5 feet of new growth per year.
• Years 6+: Less than 12 inches of new growth per year.

So in the first 5 years, you can expect your wax leaf privet to reach its mature size of 8-10 feet tall and 4-6 feet wide. The growth rate depends on a few key factors:

Key Factors Influencing Growth Rate

Sunlight

The wax leaf privet thrives in full sun to partial shade. Plants situated in full sun are able to produce food through photosynthesis and will grow faster than those in heavier shade. Provide at least 6 hours of direct sunlight per day for optimal growth.

Soil Conditions

This plant is adaptable to different soils, as long as the soil drains well. Rich, loamy soil with added organic matter will encourage the fastest growth. Very dense or clay-heavy soil can restrict root development and slow down growth.

Watering and Nutrients

Consistent watering and annual fertilization ensures strong growth each year. Drought stressed plants allocate resources to survival rather than new growth. Apply a balanced, slow-release fertilizer each spring.

Pruning and Damage

Frequent pruning or shearling into formal hedge shapes will reduce the privet’s growth rate. It expends energy regrowing foliage instead of expanding outward. Also, any major damage from pests, diseases, weather, or mechanical injury can temporarily stunt growth.

Plant Health

A healthy, well-cared for wax leaf privet will grow faster than one plagued by issues like root rot, nutrient deficiencies pests etc. Monitor for signs of illness and treat any problems promptly. Preventive care is key for optimal growth.

Growth Rate in Different Regions

The potential growth rate also depends on the climate where the wax leaf privet is planted:

Warm Climates (USDA Zones 9-11)

In frost-free climates, the wax leaf privet can grow steadily all year long. It may achieve 2 feet or more of new growth per year. Provide ample water and nutrition to fuel this rapid expansion.

Cool Climates (USDA Zones 7-8)

Cooler zones have more seasonal variation in growth. The privet grows actively in spring and summer but goes dormant in winter. It may put out 1 to 1.5 feet of new growth per year in these areas.

Container Growth

When grown as a container specimen, the wax leaf privet’s growth rate depends on how consistently the owner maintains ideal growing conditions. A container privet may grow 1-2 feet per year with attentive care and fertilization. Growth will be slower if the plant is frequently moisture stressed.

Caring for Your Wax Leaf Privet

Now that you understand this plant’s growth patterns, you can provide proper care to achieve your goals. Here are some tips:

• For a taller, fuller hedge more quickly, plant in full sun and enrich the soil with compost or manure.

• To keep hedge growth under control, shear or trim new growth several times per year.

• For the fastest growth of a single plant, select a bushy form like ‘Texanum’ instead of a narrow upright form.

• Water container plants daily in warm weather and fertilize monthly during the growing season.

• In cold climates, limit spring pruning to avoid removing new growth that protects from winter damage.

• Monitor for pests like thrips that can slow growth if populations explode.

With the right growing conditions and care routines, you can expect your wax leaf privet to fill out at a vigorous pace. Pay attention to its growth rate and respond accordingly with pruning, watering, or troubleshooting to keep it looking its best.
